The beast of the early 2003, undisputed SSDF leader, undisputed Playchess Engine Room favorite Shredder 7.04 stands up against the current leader:



A game [D]q7/5pkp/3p4/p2P3r/5P2/P1Q5/1PP5/2KR4 b - - 0 29[/D]

Observing the games, Houdini outplays Shredder in the opening, if not finished, in the middlegame, and if not finished, then surely in the endgame. Tremendous achievement in these less than 10 years.

Actually there are something between 400 and 500 ELo between them.

You where lucky that Shredder got 0.5 Points ....

On your list Houdini 3 vs Shredder 10 difference is 500 points, I believe the difference from Shredder 7.04 is about 600 points, and probably more if Bayeselo compresses ratings. My TC is shorter, 1'+1'', maybe this exaggerated difference a bit. I will play another 200 games to see more draws

Kai

Yes you are right (bad calcualtion by me).

600 Elo difference might be about right ...even more supprised am I to see a draw

Quite laughable
I hope the trend will continue for the next 10 years

May be H3 tactical will do even better because it will kill more faster in the middle game !

That's an interesting perspective, I've made an entry on the Houdini Facebook page about it.
From Shredder 7's point of view, Houdini 3 is playing virtually perfect chess.

Will it be possible to sustain the 50 Elo/year software improvement over the next 10 years?

I put them to play another 200 games at 1'+1''. Both are on one core. The result is +197/=3/-0. The total is +296/=4/-0. Yes, if I came with Houdini 3 back then claiming that it solved chess, it would have been hard for folks to disprove me using the "beast" of its time Shredder 7.04.

2003 was the year when Kasparov played Deep Junior and Kramnik Deep Fritz, both to a draw in matches of 4 games. Shredder 7.04 was the undisputed leader, and I had a healthy respect for its play. To see it dumped like a novice (two thirds of the games finished in under 48 moves) is amazing.

Maybe the trend of +50.. +60 per year can hold, today we cannot imagine something making fun of Houdini 3, 10 years ago I couldn't imagine seeing Shredder in that position.

The result is more than I expected from the rating lists, and there are 2 standard deviations that Houdini 3 scores in excess of 740 points above Shredder 7.04, maybe the rating lists deflate a bit the rating differences on such large intervals.

Tremendous progress.

It is clear that houdini3 outsearches Shredder7.04 and get bigger depths.

I wonder what is the hardware that you used and how many cpu did the engines use?

It is also interesting to know if shredder may get more draws at longer time control.
